Specification of Letters Patent.

Patented Apr. 23, 1912.

Application filed April 28, 1911. Serial No. 623,956.

b all whom it may concern:

Be it known that 1, Jones RonvER, of the city of New York, county ofQueens, and State of New York, have invented a new and usefulImprovement in Bed-Springs, of which the following is a full, clear, andexact description.

My invention relates to improvements in bed springs, and the object ofmy invention is to produce a simple, inexpensive, and exceedinglyresilient and easy bed spring which can be easily applied to an ordinarybed and is easily removed, which is adapted to have a perfectly flat andyet resilient surface, and further to provide a bed spring in which thesurface is formed of longitudinal parallel inelastic bands which at theend portions are each connected with spiral springs so as to pulllengthwise on said springs, thus giving resiliency to the bands, andalso to provide spring bolsters which are adapted to l e beneath thebands of the main springs and which by being movable can be made tosupport the main surface of the bed spring at any desired point.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar reference characters indicatecorresponding parts in all the views.

Figure 1 is a plan view of a pair of bed springs embodying my invention,the same being shown in position on a bedstead. Fig. 2 is a brokenenlarged detail plan of one end portion of the bed spring. Fig. 3 is abroken inverted plan of the structure shown in Fig. 2. Fig. 1 is abroken side elevation of the spring as applied to a bedstead. Fig. 5 isa detail side elevation of one of the spring 1001- sters. Fig. 6 is adetail sectional view showing one of the end supports for the spring,and Fig. 7 is a detail cross section on the line 77 of Fig. 2.

The bed spring has side rails 10, which are preferably of angle iron, toform a convenient support for the bolsters hereinafter referred to, andthe side rails are connected by cross pieces 11 near the ends and bycross rods 12, any necessary number of cross pieces and rods being used.At the ends of the bed spring and a little above the bed portion thereofare transverse shafts 13, each being provided with a series of rollers14 which are spaced apart and grooved slightly so that the bands 18hereinafter referred to may run smoothly on them and fit snugly in thegrooves so as to leave the top surface flush with the surface of therollers. Each shaft 13 is supported in a series of braces 15 which arein turn mounted on the cross rods 12 and 16 which connect the side railsof the bed spring near the ends. Each end of each band 18 is connectedwith a spiral spring 17 which is also attached to the cross rods 16. Therollers lt are fitted to run smoothly and, it will be seen that whentension is applied to the bands 18, as by a person lying on the bedspring, the tendency to sag is resisted by the tension of the spiralsprings 17, while a very easy bed is afforded by the longitudinalresilience of the springs 17 It will also be noticed that each band 18is an independent unit and that the bed is therefore very comfortable tolie on. It will further be observed that by this construction thetendency to produce a permanent depression in one part of the bed isobviated, and further that by this construction two bed springs caneasily be applied to a double bed as shown in Fig. 1, and the depressionof one part of the bed spring will not affect the other part, as is thecase where a full woven surface on a sin-' gle spring bed is used.

The arrangement just described produces a very comfortable bed, but somepeople, either through excessive weight or for other reasons, prefer abed that will not be so resilient, and to meet these requirementsIprovide bolsters l9 and 19 which are themselves resilient but which canbe slipped along underneath the bands 18 so as to stiffen these, and atany necessary point. Each bolster is provided with top and bottom rails20 and 21 which are spaced apart by the vertically arranged helicalsprings 22, and the bottom of each bolster is provided with ledges 23adapted to rest in and run along the angle iron rails 10 of the bedspring. The top and bottom rails of the bolster are also connected byguide rods 24 which are secured to the top 20 and slide freely throughthe bottom portion of the bolster. At the right hand in Fig. 1 I haveshown the bolster with two top rails 20 and a corresponding double setof springs 22, while at the left hand in Fig. 1 this arrangement isshown in triplicate, but obviously a greater or less number of banks ofsprings 22 can be used as desired.

Any suitable bedstead, as for instance the bedstead 25, can be used inconnection with the bed spring, and I prefer to have the bedsteadprovided at the ends with ledges 26 preferably in the form of angleirons, so that the bed spring ends may be laid on these ledges, and bymaking the bed springs in single bed sizes and using two of them on onedouble bed as shown, the springs are easily handled and can be placed onor removed from a bedstead without injury to either the bed springs orthe bedstead. Attention is called to the fact that the parallel bands 18can be rigidly supported at one end if desired, and a cheaper bed springproduced, as the resiliency of the springs 17 at one end will answer thepurpose very well, but I prefer to make the bed spring double ended asshown.

It will be understood from the foregoing description that the particularmeans for supporting the ends of the bands 18 of the bed springs can bedeparted from without affecting the invention, but the generalarrangement of the bands and the mainte nance of their tension bylongitudinally arranged spiral springs, should be preserved.

I claim 1. A bed spring comprising a base or frame, a series of parallelinelastic bands forming the bed spring surface, a separate rotatableguide or support for each band near its ends, and longitudinallyexpansible springs secured to the ends of the bands and to the frame ofthe bed spring.

2. A bed spring comprising a frame, a transverse shaft supported at eachend of the frame, a series of rollers supported on the shafts, inelasticbands extending lengthwise of the frame and passing over the rollers,and a transverse support for the bands, said support being slidablelongitudinally on the frame and having its top and bottom portionsspaced apart by springs.

8. A bed spring comprising a base or frame, transverse shafts at the endportions of the frame, braces spaced apart to support the shaft, aseries of rollers on each shaft, inelastic bands extending lengthwise ofthe frame and passing over the said rollers, and a pair of spiralsprings for each band, said springs being attached to the ends of theband and to an adjacent support on the frame.
